Note:
Do not confuse the Print preset with the Press preset. The Print preset exports Adobe
PDF files that output well to desktop printers and proofers, and the Press preset exports PDF
files for prepress output devices.
•
Press.
Creates Adobe PDF files that will be printed as high-quality final output to an
imagesetter or platesetter, for example. In this case, output quality is a much higher priority
than file size. The objective is to maintain all the information in an Adobe PDF file that a
commercial printer or service provider will need to print the document correctly. This PDF
export preset does not convert color spaces, downsamples color and grayscale images to 300
dpi and monochrome images at 1200 dpi, embeds subsets of all fonts used in the file, sets
the High Resolution transparency flattener preset, and uses other settings to preserve the
maximum amount of information about the original document.
•
PDF/X-1a.
Creates Adobe PDF files that conform to the ISO-standard PDF/X-1a specifica-
tion. The objective of this standard is to deliver a file that is ready for high-resolution CMYK
output. Compression settings are identical to the Press preset. The PDF is generated for PDF
1.3 (Acrobat 4) compatibility, colors are converted to CMYK as the output color space, and
OPI content cannot be omitted. You can preflight PDF/X-1a files in Acrobat 6 Professional.
•
PDF/X-3.
Creates Adobe PDF files that conform to the ISO-standard PDF/X-3 specification.
The objective of this standard is to deliver a file that is ready for high-resolution output
within a CMYK workflow or within a color-managed RGB workflow. Compression settings
are identical to the Press preset. It doesn’t allow security settings. In other respects it’s identi-
cal to PDF/X-1a.
•
Acrobat 6 Layered.
Creates Adobe PDF files that conform to PDF 1.5. Compared to other
presets, Acrobat 6 Layered adds support for content layers and JPEG 2000 image com-
pression. Compression settings are identical to the Press preset, and color is set to Leave
Unchanged.
You can’t edit or delete the built-in PDF export presets. If you want to use settings that are
similar to or based on a built-in PDF export preset, simply create one using a built-in preset
as a starting point. If you base a preset on PDF/X-1a or PDF/X-3 by selecting one of those
standards from the Standard pop-up menu in the General dialog box, the choices available
to you in the rest of the PDF Export Preset dialog box are constrained to maintain confor-
mity to the standard you chose.
